Web26 Nov 2024 · Whether you're performing food, environmental, or clinical analyses, Restek's PAL SPME Arrow can quickly become an indispensable tool. This fast and automate... WebSPME is an innovative solvent-free technique introduced in 1989 by Pawliszyn and co-workers5that combines sample extraction and concentration in a single step. It consists of a fiber coated by an organic phase that acts by extracting and concentrating the analytes present using selective absorptive/adsorptive processes.
Application Note - Agilent Technologies
WebSPME Arrows can be applied in headspace analysis or by liquid immersion to concentrate an analyte on the Arrow. SPME Arrows are up to 10 times more sensitive than SPME fibers. … WebSPME fibers have been selected as sorbent material - Carboxen/PDMS SPME fibers and Carbon WR SPME Arrow were compared. Carbon WR SPME Arrow gave a 3-5 x higher extraction yield/detector signal. - The limits of detection (= S/N > 3) range from 5 ng/L for N-nitroso-dipropylamin to 50 n/L for N-nitroso-pyrolindin-amine. top 50 richest people in south africa
